Douglas and Zeta-Jones back on red carpet - The West Australian

Estranged couple Michael Douglas and Catherine Zeta-Jones have made their first red carpet appearance together in a year to Steven Soderbergh's new off-Broadway play.

The pair separated in 2013 after 13 years of marriage, however, recent reports suggest they are working on giving the marriage a second chance.

On Tuesday, the two put on a united front during a rare public outing while attending the opening night performance of Soderbergh-directed production The Library at New York's Public Theatre.

Both Zeta-Jones and Douglas have worked with the acclaimed filmmaker in the past - they both starred in Soderbergh's Traffic, while the Welsh beauty appeared in Ocean's Twelve and Side Effects. Douglas collaborated with the director on Haywire and Behind the Candelabra.
